CAR-ODUPLING.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed March 31, 1910. Serial No. 552,653.

To all whom it may concern:

Be it known that 1, CHARLES ROSENZWEIG, a resident of Pittsburg, NorthSide, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Car Couplings; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to car-couplings.

The object of my invention is to provide a cheap, simple and efficientcar-coupling, in which double locking means for the same is enabled whenthe device is employed for connecting two cars together, as well as onewhich will be positive and reliable, will be quickly and easily operatedin coupling or uncoupling, and will be strong and durable, inexpensiveto manufacture by being composed of few parts, and will not be liable toget out of order.

T 0 these ends my invention consists, generally stated, in the novelarrangement, construction and combination of parts, as hereinafter morespecifically set forth and described and particularly pointed out in theclaims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved car-coupling, I will describe the samemore fully, referring to the accompanying drawing, in which Figure 1 isa top plan view of my improved car-coupling. Fig. 2 is a horizontalsectional View on the line 2-2 Fig. 3, looking in the direction of thearrows. Fig. 3 is a longitudinal section on the line 33 Fig. 2, lookingin the direction of the arrows. Fig. 4 is a cross-section on the line4-4 Fig. 1, looking in the direction of the arrows. Fig 5 is aperspective view of the looking member. Fig. 6 is a perspective View ofthe knuckle. Fig. 7 is a side view of the engaged couplers. Fig. 8 is aplan view showing one of the couplers in engagement with the ordinaryapproved coupler.

Like symbols of reference herein indicate like parts in each of thefigures of the draw- 1n As illustrated in the drawings my im provedcar-coupling is provided with the coupler heads 1, which have the jaw 2and forwardly extending arm 3 within each of the same and on oppositesides from each other. Between the jaw 2 and arm 3 is the shoulderedextension 4 in each of the heads 1 and within each of said arms and saidheads is a horizontally extending cavity 5 in which a knuckle 6 ispivotally mounted on a pin 7 extending through the same and the head.The knuckle 6 is provided with an inclined face 8 011 the inner or. tailend of the same which terminates in a curved or rounded inner portion 9,and a tongue 10 is formed on the other end of said knuckle.

lVithin each of the heads 1 is the locking member 11, which ispivot-ally mounted at one end in the cavity 5 in said heads by means ofa pin 13, and its opposite end 12 is provided with the double inclinedfaces 12 and 12. The pin 13 is secured to the member 11 by a squaredportion 14, and is provided with circular portions 15 beyond saidportion for being ournaled in the head. The locking member 12 isnormally held in a fixed position by means of a spiral spring 16, oneend of which fits within a seat 17 in a boss 17 on the head 1, while theother end of said spring fits within a like slot 19 in said member. Alever 20 is secured at one end to the squared portion 15 on the upperend of the pin 13, and the other end of said lever is preferablyconnected to one end of a chain 21, which leads back to the usualoperating crossbar (not shown) on the car and is connected thereto inany suitable manner for opening the locking member 11 carried by saidpin through the drawing back of said chain, which bar has the usualhandles at each end of the same for opening the coupler from eitherside.

In the normal or closed position of the locking member 11, the doubledinclined end on the same is adapted to be limited in its inward movementby the tongue 10, and when in this position will prevent the knuckle 6from swinging open by the engagement of the inclined face 12 on saidmember with the inclined face 8 on said knuckle. To release the knuckle6, the pin 13 is turned by the drawing back of the chain 21 connected tothe lever 20 on said pin, which will pull the locking member 11outwardly until it clears the inclined end 8 of the said knuckle,thereby compressing the spring 16, and when the adjoining head is pulledoutwardly, the said knuckle will swing until the shoulder 4 on said headclears the tongue 10 on said knuckle, as shown by dotted lines in Fig.2, so that immediately upon said knuckle assuming this position, thelocking member assumes its normal or closed position upon the releasingof thechain 21 and the compression 'of-ther spring 16 thereby, and thetongue 10;.011 said knuckle is held in an open position as so shown bydotted lines, by the pressureof the inclined face 12 on said memberagainst the curved end 9 on said knuckle.

In coupling the heads 1 together, the aw 2 strikes the tongue 10 of theknuckle 6 on the adjoining head and forces the tongue inwardly, thecurved end 9 onthe knuckle forcing the locking member 11 :ontwardly,which will release said member and allow it to asume its normal positionin locking the the knuckle 6 of one jaw with relation to the lockingknuckleof the other jaw. 1 Theopening of the knuckle 6. is limited bythe tail end of the same engaging with the shoulder 4:, as suchknucklein-this open position is clear of the inward movement of the lockingmember 11,,and it will be observed that the knuckles 6 intheir closedposition take a positive grip on the shoulders 4t and cannot beforc'edopen until the locking members are swung outwardly, while theinclined faces on the knuckles and locking members permit of the twocoupler heads being automatically locked together.

In Fig. 8, one of the coupler heads 1 of my improved coupling is shownas being coupled by its knuckle 6 with the knuckle 6 in the head 1 ofthe ordinary approved coupler, known, as the M. C. B. type, in which theknuckle 6 is operated by the usual devices from the chain connection 21attached to the ordinary cross-bar for operating the same, and it willbe evident that other forms of couplers can be connected to said head 1,if desired.

Various other modifications and changes in the design, construction, andoperation of my improved car. coupling within the scope of the appendedclaims may be resorted to without departing from the spirit of theinvention or sacrificing any of its advantages.

What I claim as my invention and desire to secure by Letters Patentis 1. A coupler head having a knuckle pivotally mounted therein andprovided with a locking tongue at its outer end, a stationary shoulderon said head and back of said tongue when the latter is in its lockedposition, said shoulder being adapted to hold the tongue of the knuckleof the engaging couplerinv position,'and arecess in the rear of saidshoulder adapted to receive the knuckle tongue otan opposing coupler ofsimilar type, and means within said head for locking its knuckle.

2.:Acoupler head having a knuckle pivotally mounted therein and providedwith a locking tongue at its outerend, a stationaryshoulderon said headand back of said tonguein a longitudinal line substantially central whenthe latter 151111 its, locked position, said shoulderbeing adapted tohold the tongue of theknuckle ofthe engaging coupler in position, and arecess in the rear of said shoulder adapted to receive the knuckletongue of an opposing coupler of similar type, and means within saidhead for locking its knuckle.

In testimony wherof, I, ,thesaid CHARLES Rosnnzwnre, have. hereuntosetmy hand.
